MENDAL W. WILLSON, OF MOUNT CARMEL, ILLINOIS.

Application filed March 3, 1922. Serial No. 540,848.

To all whom it my concern:

Be it known that I, MENDAL W. WILLsoN, a citizen of the United States, residing at Mount Carmel, in the county of Wabash and State of Illinois, have invented certain new and useful Improvements in Ozonizers, of which the following is a specification.

My invention relates to improvements in ozonizers, and more particularly to that class or type designed to convert oxygen into ozone for commercial use such as bleaching, like.

The primary object of my invention is to provide a generally improved ozonizer of the class or type indicated which will be exceedingly simple in construction, cheap of manufacture, and eflicient in use.

A further and very important object is the provision of an improved water jacketed insulator vessel or dome together with purifying, sterlizing,- and the an improved construction and arrangement of insulator base or support having an improved nozzle or jet opening adapted to cooperate with the improved electrode.

A still further object is the provision of an improved form and arrangement of electrodes spaced a suitable distance apart to provide a silent discharge gap above the nozzle or jet opening in co-operative relation to the latter.

A still further object is the provision of an improved electrode for ozonizers of an improved form and composition. The improved electrode is preferably of triangular shape in cross section to provide sharp in terchangeable arcing edges, the electrodes being arranged in downwardly converging relation to each other and spaced apart at their converged ends to form a discharge gap immediately above the nozzle or jet opening and diverging upwardly to create a diminishing discharge zone.

A still further object is the provision of an improved arrangement and mounting of the electrodes relative to the ox'ygen nozzle or jet opening, the latter beingmade a part of the insulator electrode support and the arrangement being such that'the converging ends of the electrodes are immediately above the jet opening thereby providing a constant arcing of the electric current upon the jet of oxygen or air so that all of it passes through the arc and is therefore converted into ozone.

- I have found by practical experience in the production of ozone by an electric are that the produced ozone will destroy some of that previously produced if permitted to come into contact with hot surfaces raising the temperature above a certain degree and hence I aim to control the after temperatures in the present apparatus as much below 212 Fahrenheit as possible, since 392 Fahrenheit decomposes ozone into its original-oxygen form it being found, however, that ozone once destroyed by heat can not again be restored. It is found also that the lower the temperature of the oxygen treated by anelectric arc, the greater the percentage of ozone produced.

'With the above mentioned and other objects in view, my invention consists in the novel construction, arrangement, and combination of parts hereinaftc: described, illustrated in one of its embod ments in the accompanying drawings and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure l is a central vertical sectional view of an ozonizer constructed in accordance with this invention.

Fig. 2, a view, partly in side elevation and partly in section, of the dome portion of the insulator vessel or ozone receiver turned a quarter turn from that shown in Fig. 1 to more clearly illustrate the relative arrangement of the ozone intercepting and cooling water circulating cross tubes.

Fig. 6, an enlarged top plan view of the insulator base, detached, and illustrating in particular the elongated nozzle or oxygen inlet jet opening.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved ozonizer comprises a suit-' able base or support 1, provided, in the present instance, with a plurality of upwardly extending equally spaced supporting posts or columns 1*, said posts 1 being adapted to removably support or carry a sub-base 1", the latter, in the present instance, being no of disc shape and provided with a central opening 1, and a'plurality of bolt receiw ing openings 1".

The improved insulator .vessel or ozone receiver 2, comprises a base portion provided with an annular base flange 2", and is provided at its top with a dome portion 2*. The vessel or receiver 2 is preferably formed of glass as shown, but may be formed of some other suitable insulating material and as a means of maintaining the ozone within the chamber 2, at a temperature as much below 212 Fahrenheit as possible and providing for a substantially uniform temperature of the vessel the latter is preferably provided with outer and inner walls 2 and 2 respectively, forming an annular water circulating space 2, the latter communicatingwith an inlet neck 2, provided with a conductor tube or hose 2 communicating with a suitable source of fresh water supply, the upper portion of the dome being provided .with an outlet neck or nipple 2, provided with a flexible pipe or hose 2, for the outlet of the heated water after it has passed through the water passage.

As a means of intercepting and cooling the ozone directly over and coming in contact with the hottest ozone above the electric discharge zone below between the electrodes, the inner wall 2 is provided with a plurality of cross water circulating pipes or tubes 2 As a means of providing for the outflow or conveyance of the ozone to the desired place of use or storage. the dome portion is provided with an outlet neck 2*, the latter, in the present instance, being provided with a flexible conduit pipe 2.

As a means of sealing the point of contact between the base flange'2 and the sub-base 1 the latter is provided on its top with a gasket 3. and as a means of clamping the base of the vessel to the base 1 a two-part flanged clamping ring 4, may be provided, said ring 4 being provided with suitable bolt receiving openings to receiving clamping bolts 5 threaded into suitable threaded openings in the posts or supports 1.

The insulator base 6 is provided with a suitable hub or neck portion having an interior opening terminating at its top in an upwardly tapered outlet or dome portion 6', the latter terminating in an elongated or slotted fresh air or oxygen jet opening 6".

As a means of delivering the fresh air or oxygen to the upwardly converging or dome portion 6 and jet opening 6 a vertically extending delivery tube 7 is threaded in the central threaded opening 1 of the sub-base and as a means of insulating and sealing the tube 7 with respect to" the insulator base 6 a rubber gasket 8, surrounds the tube 'i' and is interposed between the insulator and the base plate 1". The delivervtube 7 is connected to a suitable fresh air supply or oxygen pipe 9 leading to a suitable source of supply.

In the present instance, the insulator base is provided with arms having slots 6, the latter being adapted to removably and adjustably receive electrode supports 10, the latter, in the present instance, being in the specific form of upwardly extending sup-l porting stems or arms terminating at their tops in clamping heads 10 the lower ends of the arms or supports 10 being threaded and being connected and clamped by means of washers 11, and clamping nuts 12. The electrode supports 10 are provided with suitable conductors 13, suitably connected to suitable conductors 14:, arranged within suitable high potential insulators 15, the conducting portions 14 of the insulators 15 being connected to the conductors or terminals 16, leading to the transformer. The clamping heads 1O are provided with undercut sides conforming to the form of the inclined sides of the improved electrodes hereinafter referred to, said clamping heads-10 being provided with clamping screws 17 and nuts 17, as shown most clearly in Figs. 3 and 4 of the drawings.

Referring now to the improved electrodes 18 and improved manner in which the same are mounted and arranged relative to each other and with respect to the elongated jet opening 6". it will be seen that the electrodes are of substantially triangular shape in cross section thereby presenting relatively sharp edges 18, and relatively sharp terminal points 18", so that when the electrodes are arranged in downwardly converging relation as shown most clearly in Fig. 1 of the drawings the terminal points 18 will .be disposed immediately above the jet opening 6 and the oppositely arranged sharp edges 18 extending upwardly and in diverging relation will crcate a diminishing discharge zone upwardly from the jet opening and between the electrodes.

The electrodes 18 are preferably made of platinoid or tungsten and it will be understood that the electrodes may be readily reversed or interchanged to bring the sharp edges 18 into opposite relation to present a new discharge edge whenever desired, this interchangeable relation resulting in econ omv in the renewal of parts.
